OYRUS B. MORSE, OF RHIN EBEOK, NEW YORK.
MOLD AND CORE FOR CASTING HOLLOW lNGiOTS.
SPECIFICATION forming part of Iietters Patent No. 235,796, dated December 21, 1880. Application filed September 18, 1880. (Model.)
To all 'whom it 'may concern Be it known that I, GYRUs B. MORSE, of Rhinebeck, in the county of Dutchess and State of' New York, have invented certain new and useful Improvements in Molds and Cores for Casting Hollow or Annular Ingots ot' Steel or Homogeneous Metal, ot' which the following is a specification.
The object of nly invention is to overcome the difculty hitherto experienced in casting steel or homogeneous metals in annular or tubular form free from gas or air cavities and imperfections caused thereby. This I accomplish by the construction and arrangement of a ventilated base and cap on the mold in connection with a ventilated hollow core having a combustible element and the metal entering the mold from the bottom.
In the accompanying drawings, which represent my mold, core, base, and cap, and their combination for casting hollow or angular in gots, Figure l is a plan view of the mold, core, base, and cap, and manner of connecting and securing the same to the runner-plate. Fig. 2 is a vertical section of the same. Fig. 3 is a plan view of the cap. Fig. 4 is a vertical section of the cap. Fig. 5 is a vertical section of the core-plate, rods, and loop. Fig. 6 is a plan view of the base. i
In the drawings similar letters of reference represent like parts.
A is the runner-plate. e c are channelopenings in same. B is the center runner. b b are runners in base of mold, connecting with same. G is center opening in cap. c c c care conical openin gs in same. Dis the core-plate and connected rods and loop. d is the opening in the core-plate, and d are the vents in the sides ofthe core. E is the mold. c c are the ears on same. F is the cap. j' f, are the ears on same. G is the bar that secures cap and core to mold. g g are small wedges for same. H is the base. 7i is the rim on same. Iis the center hole through same. K is the clrcular recess to receive core-plate in same. L is the core.
The runner-plate A is provided with channel-openings a a., extending inward and connecting with the center hole, I, in the base of' escape of gas and The base H has a rirn, lz., around it, to reeeive and hold in place the moldiE.' It hasin its center a circular recess, K, to receive, center, and hold in place thelower end of the core, L. In the center of this recess is a hole, I, runnin g through the base H, forming, with the channel-openings a a in the runner-plate A and the opening d through the core-plate and vents d in the core and cap O, a conduit for gas and air.
The core-plate has rods attached at opposite points. rlhese rods are slightly longer than the core, and are united together, the top being arched, so as to form a loop above the core, for the purpose ot' carrying, setting, and holding the core in place. llhe core is made upon this plate around these rods, and has a hole through its center. rlhe core is iliade of a mixture one element (for instance, unbolted our, sawdust, pitch, dac.) ot' which is colnbustible, and the walls of the core are vented. The core is made slightly tapering from bottom up.
The top of the mold E is closed with a .recessed cap, F, which its inside of the mold and rests upon it. rlhe cap has a hole through its center, O, to receive the core L and keep it central at the top ofthe mold. rlhe cap F has conical openings or vents c c c c, to admit ot' the free escape of gas or air that may be between the mold and core while the met-al is being poured. rlhe cap F lias two ears, ff, at opposite sides for theV purpose ol' holding it in place.
The mold ina-y he made of cast-iron or other suitable metal, may be of' any convenient form, the interior to be slightly tapering from the bottom up. It is to be provided on the top with ears c c upon opposite sides, so constructed as to hold the bar Gr or other suitable device, to keep the cap and core in place. The cap F and core L are secured in place by a bar, G, passed through the ears c c on the mold E, over the top of the core-loop I), and over the ears j j' of the cap F, the wedges g g making the connection lirm and secure.. v
The metal enters the mold at the bottom b b, being poured through a center runner, B,
onnecting;` with each mold that maybe in the luster. The gases and air escape through the onical openings in the cap and through the ents in the core. rlhe gases which escape )rough the vented core and the combustible lement of the core become ignited and are ansuined. The oxygen to support combuson is supplied through the openings conected with the hollow core. A draft is thus stablishcd within the core and the Q;ascs nrc rawn through the vents and consumed.
rlhe pressure caused by the metal being;` )rced into the mold from the bottom up gainst the cap will solidify it.
What I claim is- 1. A mold having,` a ventilated base, in comination with a runner-plate and connecting hanncl grooves or openings therein, and a ollow core to admit ot the free passage of `@,as nd air through the base and core, substanally as and for the purpose described.
2. A hollow core havin g vents d in its Walls, in combination with a mold having a base and cap, substantially as and for the purpose described.
3. The combination of a mold with a ventilated basc, ventilated cap, and hollow core having vents therein, substantially as and for the purpose described.
4l. Ahollow core having vents d in its walls, and composed, in part, of combustible matc- .rial, in combination with a mold having ventilating-openings at cap and base connected with the interior opening of the core, substantially as hereinbefore set forth.
